Question

I have working code I developed for a linux server that when I have tested locally using WAMP have started to get strange Xdebug errors of the form

Notice: Use of undefined constant fullName - assumed 'fullName'

The code is…

$allVars = array(
    fullName=>$fullName, 
    telephone=>$telephone,
    email=>$email,

    fAddr=>$fAddr,
    tAddr=>$tAddr,
    sngRtnSelect=>$sngRtnSelect,
    oDate=>$oDate,
    rDate=>$rDate,
    tAdditional=>$tAdditional,
    noPassengers=>$noPassangers,
    vehicleType=>$vehicleType,
    distance=>$distance,
    priceTot=>$finalPrice

); 

I thought the above was a straight forward array definition. Could anyone shed light on why such errors are appearing on WAMP and not the linux server?

If I have missed something obvious, then my apologies, however this is the identical code that worked on the linux/apache server. Thanks.

If you are defining a string key then you should put it inside quotes. Like this:

$arr = array ( 'some_key' => 'some_value' )

However, when you are working with integers you should not use quotes, otherwise you’ll create a string.

$arry = array ( '0' => 'this is a string key because it has quotes around.', 
                 0  => 'this is an integer key because it has not quotes around.');

By the way, when you do not use quotes for a string value, it means that you refer to a defined variable.

define ( 'name', 'Savas Vedova' );
echo name; // this will print Savas Vedova to the screen.
